    hi, I just bought a Mac Pro 2009 2.66 (i think) with 3 Gb ddr3 ram and the stock graphic card.
    I know the graphic card is not working but thats ok since i have a 660Ti laying around i can use.
    Now the problem is the Mac does not have a HHD or / SSD so i need to buy one, also okey, was planing on doing it anyway, same with more ram.
    but am not sure how to download an old OSX because i need and older i think..? well am not sure about this part. so... can anybody tell me how to proceed from her

    I don't think Lion can drive 660Ti. From memory, this GPU required 10.8 or later.

    Also, Apple never has sold Lion on a DVD. You purchase Lion from that linked page, and Apple sends you a redemption code that you use in the App Store to download the Lion installer.

    Get a Mac version gt120.
    Which was factory for your tower.

    Then you can install whatever OS and then swap your card.

    GTX 660 Ti needs at least OS X Mountain Lion 10.8.3. You will have no boot screen with a PC GTX 660 Ti.

    If you would have an Apple graphics card or EFI-flashed card you could install OS X 10.6.8 from DVD (an run without graphics acceleration), and upgrade over the App store to OS X El Capitan. But you don't have an EFI Card, so no chance to install 10.6.8 from DVD.

    - Ask a friend for an SSD with Mountain Lion, Mavericks or El Capitan already installed, install the SSD in the Mac Pro, do the Mac Pro firmware upgrade 4,1 -> 5,1*, and you are able to install the newest MacOS Sierra.

    * I forgot: Mac Pro firmware upgrade only possible with an EFI graphics card.

    - Upgrade RAM at least to 8 GB

    I use Mavericks 10.9.5. It seems the most stable for my requirements but I recently installed Yosemite on a spare drive as it loads my ASM 1042 USB 3.1 card natively.

    You could pick up a used snow leopard DVD off eBay and upgrade from there

    No, he can't install Snow Leopard with a normal PC GTX 660 Ti -> black screen
